| 論文概要（英文） | Sea buckthorn (Hippophae rhamnoides L.), a shrub belonging to the family Elaeagnaceae, is widely distributed across Eurasia, including Mongolia.1 The fruit is renowned for its rich content of vitamins, carotenoids, and unsaturated fatty acids such as oleic, linoleic, linolenic, and palmitoleic acids. Palmitoleic acid, particularly notable in the pulp oils, has demonstrated beneficial health effects, including lipid regulation, antioxidant activity, cardiovascular protection, and anti-aging properties. Carotenoids like β-carotene and zeaxanthin contribute significantly to the oil’s antioxidant capacity and skin-protective effects against UV radiation. However, the poor oxidative stability, absorption, and solubility of these bioactive compounds limit their functional application in food and pharmaceutical industries. This study investigates the potential of native cyclodextrins (CDs) to enhance the stability and bioavailability of carotenoids and palmitoleic acid in sea buckthorn oil (SO). SO-CD powders were prepared via homogenization and freeze-drying. Samples were dissolved in water and simulated intestinal fluid, shaken at 25-37°C and 160 rpm for 2 hours, then filtered for analysis. Solubility in simulated intestinal fluid can predict bioavailability. Carotenoid content was calculated by measurement of absorbance at 450 nm, and palmitoleic acid was quantified via GC-FID. The oxidative stability was assessed through the Rancimat method. |
